Description

 The invention relates to medicine, in particular to conservative therapy, and can be used to biostimulate the body in order to eliminate pain, inflammation, edema syndromes, improve local and general blood flow, tissue regeneration, increase defenses, etc.

 Known devices for biostimulation, based on the use of radiation in the optical range - ultraviolet, visible, infrared ("Handbook of Physiotherapy" edited by V. G. Krasnogorodsky. -M .: Medicine, 1992, p.15-18).

 However, the last 30 years in medicine, devices have been used that generate monochromatic coherent (laser) and incoherent (LEDs) radiation in the optical range, which is a more effective biostimulator (V. I. Kozlov, V. A. Builin, “Laser therapy”, Moscow- Vladivostok, 1992).

 A device for laser-light therapy and magnetic therapy is known - Isel (USSR patent N 1273895, BI N23), which uses monochromatic incoherent infrared radiation with a power of up to 40 mW.

 A device for light therapy - "Spectrum" (Sat. Teach, Proceedings Int., Conf. "New Achievements of Laser Medicine", Moscow - St. Petersburg, 1993, S. 309-311, 580-581), including a power source with control unit. The case for the radiator in the form of a cylinder of plastic with a diameter of 5.5 cm, height 4.5 cm, in which 16 LEDs with a total power of up to 100 mW are mounted, the mass of the radiator is 100 g.

 However, all of the above devices do not allow treatment without an operator due to the massiveness of the emitter, which leads to constant exposure to operator light.

 The devices use low-power LEDs, which often fail, the radiation of which, in our opinion, is insufficient for effective treatment. The emitter enclosures do not provide heat dissipation, therefore, powerful LEDs cannot be used in them, since they can lead to overheating of the case and, as a result, burns to the patient's skin.

The proposed device (Fig. 1-3) consists of a power source with a control unit and a metal casing connected to it by an electric cord for an emitter in the form of a cylinder, in which an “Ostyanyak” brand LED is integrated, generating a monochromatic (wavelength 0.87 μm) incoherent infrared radiation up to 200 mW. The height and diameter of the cylinder is 32 mm, the wall thickness is 6 mm. On the outer surface of the cylinder circular grooves (8 pieces) are cut 4 mm deep and 2 mm wide, which are radiators for heat removal. One of the ends of the cylinder is closed with a metal stopper with a thread, and on the other hand an LED is inserted. The control unit has one button that performs the functions of "Start" and "Stop". The presence of a timer for 3 and 5 minutes, a power regulator with two positions of 50 and 100% allows you to use 4 exposure programs:
1st - 50% of power for 3 minutes,
2nd - 50%, 5 min,
3rd - 50%, 5 min,
4th - 100%, 5 min.

 To study the effect of light of the proposed device on the body, we performed experimental work on 30 non-linear rats after the introduction of radioactive diagnostic particles into their body. Analysis of successive changes in organ blood flow depending on the radiation power and exposure in correlation with clinical observations allowed us to develop unified methods of treating patients using 4 radiation programs. In the first half of the course (7-12 days) of daily procedures in adults, the 4th program is used, and in children and the elderly, the 3rd. In the second half of the course, the dose is halved and accordingly prescribed for adults - the second program, for children and the elderly - the first.

 Conducted in the clinic RosNIIITO them. RR Vredena clinical trials have shown high efficiency of the proposed device with previously known. The device is portable, easy to use, safe. The insignificant mass of the emitter (up to 40 g) allows you to freely strengthen it on any part of the body without the help of an operator and at the same time does not lead to its overheating.

 Example 1. Golovkin V.A. 1936 , entered the clinic of the Institute 11.10.95, medical history N4809. Diagnosis: Deforming arthrosis of the left knee joint stage 2, flexion contracture. Complaints of pain in the joint at rest and exertion, swelling of the soft tissues, limitation of mobility in the joint.

 A course of phototherapy was prescribed using the proposed device (card N187). After the first session, swelling and pain decreased. After the 7th session, the range of motion in the joint increased, no complaints of pain. A second course, conducted a week later, consolidated the results.

 Example 2. Shields I. A., born in 1983 (Card N 179), was admitted for treatment on 10/03/95. Diagnosis: Non-healing wound of the left forearm (after a dog bite in June 1995). Twice at the institute was carried out surgical treatment - a skin transplant, but wound healing was not received. An objective examination revealed a wound measuring 2.5 cm by 5 cm, the bottom was made by pathological granulations. After two courses (7 sessions each) of phototherapy using the proposed device, complete wound healing was obtained.

 Patients mounted the emitter on the body without operator assistance; no remarks were made on overheating of the emitter.
